The atomic number is the number of protons in the nuclei of the atoms of an element. The atomic number is unique to each individual element.
The concept of atomic number was developed by physicist Henry Moseley in 1913. Moseley's work on X-ray spectra led to the realization that each element had a unique atomic number, which directly correlates to the number of protons in its nucleus.
On observing the X-Ray spectrum with increasing atomic numbers Henry Gwyn-Jefferies Moseley developed the concept of atomic numbers. By testing Bohr's and Broek's hypothesis he was able to arrive at the conclusion.
On very early versions of the Periodic Table the elements were organized by atomic mass, because it was measurable and the concept of atomic number was unknown. After Rutherford and Bohr developed their model of the structure of the atom, the Periodic Table was reorganized by atomic number (which caused a few elements to swap positions).
The concept was developed by Aryabhatta, in the Gupta empire in India.
The concept of atomic number was discovered by the scientist Henry Moseley in 1913. He found that the number of protons in an atom's nucleus determines its identity, which led to the organization of the periodic table based on atomic number.
concept of authority developed
He determined the number of positive charges in the nucleus of an atom. He was the first one to bring the concept of atomic number.

How atomic excitation lead to concept of laser?
An atom's atomic number tells which element it is. The atomic number of an element is equal to its number of protons. The number of neutrons may vary within an element, giving rise to the concept of isotopes.
The concept of atomic number was proposed by Henry Moseley, a British physicist, in 1913. Moseley's research on X-ray spectra of elements led to the reorganization of the periodic table based on atomic number. His work established the modern understanding of the organization of elements by their atomic numbers.
Yes, there were books written about the concept of atomic energy and the potential for atomic bombs before they were actually developed. One notable example is H.G. Wells' 1914 novel "The World Set Free," which featured a speculative portrayal of atomic bombs and their impact on society.
